Mobile device supporting wideband operation

Abstract

A mobile device supporting wideband operations includes a main radiation element, a first feeding element, a second feeding element, and a nonconductive support element. The main radiation element has a first slot and a second slot. The first feeding element is coupled to a first signal source. The first feeding element extends across the first slot. The second feeding element is coupled to a second signal source. The second feeding element extends across the second slot. The nonconductive support element has a first surface and a second surface which are opposite to each other. The main radiation element is disposed on the first surface. The first feeding element and the second feeding element are disposed on the second surface. A first antenna structure is formed by the first feeding element and the first slot of the main radiation element. A second antenna structure is formed by the second feeding element and the second slot of the main radiation element.
